Defogging Your Glasses | Why Glasses Fog Up & Simple Solutions

It's that time of year again, the seasons are chopping and changing, and colds and allergies are on the way. And with those pesky little viruses come a slew of annoyances, like congestion, coughing, and sneezing, which means frustratingly foggy glasses. 

One of the most common complaints about fogged-up glasses is difficulty seeing clearly, a problem that can be especially frustrating when you're trying to get work done or drive in traffic. 

 

Why do glasses get foggy?

Glasses tend to fog up when there is a sudden change in the temperature of the environment. You’ve probably noticed how when you step inside after being in chilly weather, your glasses almost immediately fog up. The same happens when you’re spending a humid summer's day outdoors and then you walk into a crisp, air-conditioned room. This phenomenon is known as condensation and is the usual culprit when it comes to foggy glasses.

We also can’t forget how masks have changed our everyday experience with glasses. Warm breath can escape from our masks and when it hits the cold surface of our glasses, our vision is impaired by condensation.

Tips and tricks for defogging glasses

Simply waiting for our glasses to clear up isn’t a practical solution. Not only can the experience be aggravating, but it can also be dangerous when you’re driving in traffic, cooking over high heat, or going for a run. 

When we’re finding solutions to the problem of misty glasses, we’re also looking for an antifog method that isn’t a temporary solution. We need an anti-mist solution that can last an extended period of time. 

Likewise, we also need a solution that isn’t going to be toxic, nor one that is going to damage the surface of your lenses. 

 

  • Defogging wipes

Defogging wipes are a handy, reliable means of keeping your lenses fog-free. These nifty little wipes are stored in little sachets, so they’re easy to keep in your glasses case, handbag or wallet. 

Unlike most lens sprays, defogging wipes are specifically designed for glasses. Once the wipe has been applied to the surface of the lens, the chemical liquid creates a surface that makes it harder for water droplets to attach to your lenses. This makes it much less likely that condensation will create large droplets that obstruct your view. 

Don’t let the idea of the wipes containing a chemical put you off; the chemical agents are completely safe and can be used when wearing masks. They can be applied before you head into the office, embark on an outdoor adventure, or before situations that require wearing a mask.

 

  • Soap and water

If you’re at home and experience foggy glasses, you’ll be delighted to know that your common household friend, soap, can reduce the surface tension on your lenses. This trick can also be used before you apply defogging wipes. 

Start by wetting your glasses and then lathering them up with soap. Give them a good wash, ensuring that you get within the corners and that the entire surface has been cleaned. Rinse off the soap and dry them off with a lens cloth or clean towel.

Top tip: Only use soap to clean your glasses. Household tricks like toothpaste, bicarbonate of soda, vinegar, and saliva can scratch the surface of the glasses or cause hygiene problems.

 

  • Lens cleaning fluid

Proper lens care can prevent a layer of dust from building up on your lens. When condensation occurs, water droplets can attach to dust particles and create hazy vision. This further runs the risk of damaging the protective coating on your eyewear. 

Lens cleaning fluid can be a quick solution when you’re on the move and you’ve noticed that your glasses have taken a bit of a beating due to outdoor conditions with dust and sand. The fluid can also be an excellent way to remove grease - grease is your worst nightmare when it comes to foggy glasses because it prevents you from wiping fog efficiently off your specs.   

It can be tempting to clean your lenses as often as possible, but if you’re constantly cleaning your lenses, you run the risk of damaging them further.

What can you use to keep glasses from fogging up?

If you wear corrective lenses, it's important to find a way to keep them from fogging up, as well as keep them protected from scratches, so you can see properly. 

 

  • Keep your glasses in a microfiber slipcase 

As we’ve noted, it’s important that we aren’t cleaning our lenses too often as it could result in unnecessary micro scratches. Not only that, but cleaning glasses too often removes the protective layer from antifogging wipes which combats condensation. A microfiber slipcase acts as a cleaner and a protector against scratches, which removes the need for excessive cleaning.

 

  • Ensure that your mask fits correctly

In today’s world, wearing a mask has become part of our daily routine. But it can be utterly annoying to constantly have blurry vision because of foggy lenses. Consider sliding your glasses further down your nose when you’re wearing a mask, as it’ll allow for air to flow between the mask and your glasses.

If you’ve noticed that your glasses slip onto your mask, consider using discreet nosepads which ensure that your frames won’t slip at all, even during a workout.  

 

  • Protect your glasses in a case

It's a fact of life that accidents happen. But with a glasses case, you can rest easy knowing your specs are safe and sound. The tough exterior protects your glasses from scratches and dust, while the soft interior keeps them free from damage. This also means that the protective layer on your lens produced by defogging wipes and lens cleaners remains intact and doesn’t wear off easily.
